Contact

No forum post yet. Go to the Issue Tracker for bugs. Look around for TechnoCat if you have any further questions or concerns.

Features

  • StayBottle, bottles that stay until a button is pressed.
  • TimedBottle, bottles that stay until a button is pressed or until a duration of time has passed.
  • Ocean, a management object for Bottles
  • Very (and hopefully easily) Configurable Bottles
  • Sleek and Stylish Bottle defaults

Missing Features

Not implemented yet, but plan to.

  • Boolean Bottles
  • Choice Bottles

Configuring

Much of the configuration you are going to want to do will take place at the top of MessageInABottle.lua.

Example

require 'MessageInABottle.lua'

function love.load()
  love.graphics.setBackgroundColor(255,255,255)
  
  --Initialize the ocean to manage the bottles.
  --It is going to act as a Queue. FIFO
  ocean = Ocean:new()
  
  --Create a timed bottle and add it to the ocean
  ocean:addBottle(TimeBottle:new(nil,"...",nil))
  
  local bottle = StayBottle:new(nil,"What is this?")
  bottle:setX(310)
  bottle:setVolume(0)
  ocean:addBottle(bottle)
end

function love.update(dt)
  ocean:update(dt)
end

function love.draw()
  background:draw()
  love.graphics.setColor(0,0,0)
  love.graphics.print(
      'last bottle return was: '..ocean.response..
      ' at '..(math.floor(ocean.responseTime*10)/10)..
      's from '..ocean.responseID,12,12)
  ocean:draw()
end

function love.keypressed(k,u)
  if k=="d" then
    local x = math.floor(math.random(400))
    local y = math.floor(math.random(150))
    ocean:addBottle(TimeBottle:new("PRESSED_D","Timed Box!"))
  elseif k=="escape" then
    love.event.push("q")
  end
end
